I glad you posted that. However, an awful lot of the videos we see (like the things I listed) are shot when people are under stressful conditions (hurricanes, accidents, etc.) and are amatures, and are excellent. So I partially agree with you. Maybe cell phones would not give good results, but we sure saw great ones of the hurricane in New Orleans, and most of those were by average people. I think some out there have teriffic skills. I even remember great shots of 9/11 that were taken by people in NY in other buildings, on the ground, etc. and what could have been more stressful than that? I guess we agree 50-50, LOL.
The simplest explanation for low numbers of videos (and that is changing)* is that UFO activity is usually very transient. A few seconds to a few minutes in most sightings. Another wrinkle is the idea that your subject matter may be intelligent and avoiding scrutiny. Intelligence meaning humans or alien.
Hurricanes, earthquakes, etc. do not practice stealth. Even surprise tsunami footage from the big one a few years ago was possible because it was a very large, non-intelligent event.
*From my reading of MUFON’s recent case files, more people are catching stuff on video these days, but it hits MUFON and other groups first, not the media.
